hvm-c segfaults with some programs

[developedby]

Describe the bug Some programs are causing hvm-c to run into a segmentation fault. As reported in https://github.com/HigherOrderCO/Bend/issues/397.

To Reproduce Run this program with bend run-c https://github.com/HigherOrderCO/Bend/files/15368994/sat.bend.txt Or the compiled-to-hvm version with hvm run-c https://github.com/HigherOrderCO/Bend/files/15368996/sat.hvm.txt

Another user reported on discord a segfault when running a simple hello world with bend run-c, but I haven't been able to reproduce

def main():
  return "Hello, world!"

User says: "I am running on WSL2 under Windows 10"

Another case of SIGSEGV in bend run-c, on Mac M1 Pro:

def testArrayMapArrayNonrecursive(_):
  * = lambda x: x+1
  return 1

def main():
  return 1

Interestingly, either removing the lambda definition or renaming the test eg. to y makes the error go away.

The renaming behaviour makes me think this might be related to https://github.com/HigherOrderCO/HVM/pull/305

I get SIGSEGV no matter the bend script I run. Any program I wrote and ran with bend run-c resulted in SIGSEGV.

This one was fixed with larger names I believe, right?

Closing as I can't reprocude. If a segfault comes up again another issue should be opened.

hvm run runs perfectly hvm run-c Segmentation fault on every program including

def main:
  return "test"

i compiled it to .hvm first then run it using hvm of cause.

hvm run-cu will cause Infinite Loop

Can you please open a new issue for this?
